Please look at the included PDF for assembly and BOM. Everything can be 3d printed without supports. Some post processing required such as drilling out 3mm holes. Total cost is around $13 USD. I also included .STEP file to be able to edited. For non-commercial use only. Thank you and have fun!!! Notes: When tightening the planet gears into the coupler, Do not fully tighten! The planets should spin freely! This is a 4.8:1 gearbox that can be modified to be used as part of an extruder, motion system, drive system, anything you want! At 16 micro-steps with a 1.8 deg nema 17 it will be about 400 steps per mm. Any questions feel free to ask!!!
